It took me a while but better later then never I guess. Some applications I tried were decent, mostly they lack something I need that is why I started using Rumbletalk. I really like that I am able to use it on my page, blog and on my facebook page at the same time as it really synchronize all the time. I was also able to manage my own design just as much as I want. Didn't find anything that it would miss with this application so I am really happy with it.
Rumbletalk also offers you the creation of experts chat room This can be placed on your website or using a direct link to the chat room.
